文本相似在问答系统中有很重要的应用,如基于知识的问答系统(Knowledge-based QA),基于文档的问答系统(Documen-based QA),以及基于FAQ的问答系统(Community-QA)等。像 对于问题的内容,需要进行相似度匹配,从而选择出与问题最接近,同时最合理的答案。本节介绍 基于ngram-tf-idf的余弦距离计算相似度。
Similarity and Distance Metrics: The dot product of two vectors is a measure of their similarity. When two vectors have a high dot product, it means they are more similar to each other. Similarly, the dot product can be used to calculate the distance between two vectors. 计算两个向量的距离...
